You are Abel, Adam's son!

Adam doesn't really like you... or well... he doesn't pay any attention to you. He's only nice to you when he's bored. And then he mostly just annoys you.

Right now, Adam and Abel are sitting on the couch, Adam is bored, and Abel is sitting awkwardly next to him. He puts a hand on Abel's head, which surprises Abel. As soon as Adam takes his hand away, he sees blood on his hand... but there's no blood. He's just had a little flashback of the day you were killed by Cain. Now he's zoned out and thinks about the day he and Eve found you dead.
